Randomized Controlled Trial
CARD (Comfort Ask Relax Distract) for school-based immunizations in Calgary, Canada: a pragmatic cluster trial.
School-based immunizations are fear-inducing events for many students and contribute to vaccine hesitancy. We developed an immunization delivery framework called the CARD (Comfort Ask Relax Distract) system that incorporates evidence-based interventions to improve the experience (eg, reduce fear, pain, dizziness). We evaluated CARD in grades 6 and 9 students in Calgary, Canada. ⋯ Immunization rate did not differ. Staff reported positive to neutral attitudes about CARD. In summary, this pragmatic trial demonstrated that CARD improved the immunization experiences of students at school.

Randomized Controlled Trial
The effect of vitamin D and omega-3 fatty acid supplementation on pain prevalence and severity in older adults: a large-scale ancillary study of the VITamin D and OmegA-3 triaL (VITAL).
A diet supplemented with vitamin D and marine omega-3 fatty acids may prevent and treat painful disorders by promoting the resolution of inflammation. However, large, randomized placebo-controlled trials evaluating the effects of supplementation with omega-3 fatty acids and vitamin D on the presence and severity of pain are lacking. VITamin D and OmegA-3 triaL-Pain (VITAL-Pain) is an ancillary study to the VITAL trial, a large randomized, double-blind, placebo-controlled trial of vitamin D (2000 IU/day) and omega-3 supplementation (1 g/day) over 5.3 years of median follow-up, among 25,871 older men and women. ⋯ There was no interaction between the 2 active treatments. Dietary supplementation with commonly used moderate doses of vitamin D or omega-3 fatty acids over a median of 5.3 years did not result in a lower prevalence or severity of pain in middle-aged and older U. S. adults.
